QULTIVATING-PLOW.

SPECIFICATION forming part of Letters atent No. 272,962, datedv February27, 1883.

Application filed September 4,1882. (Model.)

- invented certain new and useful Improvements in Cultivators, of whichthe followingis afull, clear, and exact description, reference being'had to the accompanying drawing.

In said 'drawing l have shown a perspective viewofmy improvedcultivator. It is mounted upon dri ving-wheels E E, which are connectedby an arched axle. Upon the central part, E', of said axle rests thepole or tongue, the'latter extending to a point sufncien tlyfar totherear.

My improved pole or tongue is of the peculiar form shown-that is to say,has a forwardly projecting portion, F, (preferably rounded,) and twosubstantially parallel but separated parts, F' F', all formed integrallyfrom the same beam. The slot .or open space between the rear parts, F'F', may be as wide asis desired,`though I prefer to have it merely wideenough to permit free movement of the cranks, to be described.

GGrare plow-beamssituated below andtransversely to the axle. They areliexibly supported in such manner that they can beeasily moved upwardand alsolaterally. Each beam has uprights B B, which at their upper endsare united to stirrups H H, suspended from the tongue, they resting uponthe top of the rear parts, F' F', thereof. The stirrups havedownwardly-extending legs, long enough to allow sufficient freedom ofmotion. There are eyes at the ends of the stirrups, which are connectedwith eyes in upwardly-extendlng rods b, the joint that is thus providedbeing loose enough to allow sufficient play of the beams relatively tothe stirrups.

I I are the rear plows or shovels. They are carried by arms secured att' to the beams. each arm being bent along the outer face of itsbean1,and then downwardv to a proper point to receive the plow orshovel.

I' l' are other plows or shovels, carried by arm-s fi', secured to theinsides of the beams.

D D represent scrapers situated diagonally to the line of travel, andeach secured to its beam in front of the plow or plows carried thereby.Each is attached to its beam by means of downwardly-extending rigidhangers or rods, fastened to the beam in any suitable way. The cuttersare sharpened along their lower edges, and are curved in cross-section,so that the lower edges are thrust forward to provide a bettercutting-edge.

Each of the beams and thel plows carried thereby can be mounted entirelyindependently ofthe other, if desired, though I prefer to connect themtogether at the rear ends by means ofa 'crossba`r,J, whiehis providedwith ,a series of perfor-ations at each end, by which it can beadjustably secured to projections on the uprights B B. The handles C Care carried by this connectingcross-har J, which handles are utilized bythe driver to manipulate the beams when he is walking.

The front stirrup, H, is formed or provided Witha crank, H2, between theparts F' F' of the tongue, and it will he seen that if said crank heswung backwardthe plow-beams and plows will be carried as well backwardas upward. To effect this upward and backward movement ol' the operativeparts I combine with the crank HZ another crank at K (earried by arocking bar, K', pivoted upon the upper side of the tongue) and a linkor connecting-piece, O.

A is a lever rigidly connected to the shaft K', and M is aratchetseginent adapted to hold the lever in any desired position bymeans of an interposed pawl, m, pivoted to the lever.

It' the plows approach a stump, stone, or other obstruction, they can bedrawn up by means of the lever and cranks, and if they should actuallystrike such an obstruction they can be easily disengaged therefrom,inasmuch as they are drawn backward at the same ltime that they areelevated.

If the'ohstruction is of such anaturethatthe plows cannot be. elevatedhigh enough to pass over the top, they can he swung tothe right or tothe left, owing to the flexibility ofthe counection. When the driver isseated upon the frame, he can use his feet to assistiu thus throw: ingthe movable parts to the right or to the left, stirrups heilig providedupon the inside of the standards B B for this` purpose.

It will be seen that the weight of the partsA is so distributed that itis balanced upon the axle, and therefore there is little strain upon thehorses7 necks, andthe drawing oftheplows out of the ground doesnotincrease the weight upon their necks, but rather decreases it, as aIOO greater Weight is brought to the rear ot' the axle.

A The serapers D D for the weeds end grass are so situated as to leavejust sueient space between them for the rows of plants. Being in frontof the plows,'they cutoff' all weeds and grass and turn them out towardthe center of the space between the rows, and thus remove them out ofthe wey of the plows or shovels.

l. In a eorn-cultivator, the combination of slotted pole F and stirrupsH H with the swinging plow-beams Gr, having uprights B B andconnecting-rods b, substantially as shown and described, and for thepurpose set forth.
